Problem Description:

The fiber provider from Spiez to the Jungfraujoch needs to relocate and re-splice the complete cable (96 fibers) between Zweilütschinen and Grindelwald. The cable will be cut on 14 November 2011 at 07:30. According to their schedule, we can expect our fibers to be spliced until noon. Their maintenance work will be finished no later than 16:30. As our fiber connection to the Jungfraujoch is not redundant, all services will experience a total loss of connectivity.
